--- Comment #17 from domiman@gmail.com 2010-01-23 09:51:13 --- I got a confirmation on Mike Kronenberg's site. AFAIK Mike's Wine builts are now proper Wine and not infested with all kinds of special patches. His built is up to 1.1.35 (not 1.1.36 as I previously wrote).
One thing I overlooked in the reproduction text, you need to switch to another message first and then back when you have switched from large icons to small icons. Just keeping the view on the mail with the attachement will not show the access violation when you switch icon size.
I'd still like to help figuring this out :)
